The figures in the right hand margin indicate marks. Q1 a) b) c) d) e) f) g) h) i) j) Q2 a) b) Q3 Q4 a) Answer the following questions : How would you determine the constant k and C of a tacheometer? Derive an expression for distance between the Anallactic lense and object glass Derive the relationship between the radius and the degree of curve. What are the disadvantages of a Reverse curve What is meant by strength of figure How would you determine it? Draw the figure for arrangement of (i) Double chain of triangle (ii) Braced Quadrilaterals. Write the advantages of method of correlation over the normal equation method. Explain the most probable error. List out the errors in total station. Distinguish between vertical photograph and oblique photograph. (2 x 10) Differentiate between the fixed hair method and the movable hair method. Discuss the advantage and disadvantages of each. Two set of tacheometric reading was taken from two instruments at station A, one after another, to a staff station B. Following observations obtained Determine the stadia reading with the instrument set II if the staff was held normal to line of sight and vertical angle in both the case was 28º. (5) Instrument Height of Instrument Staff Held Set I 1.364 vertical Set II 1.352 Normal to line of sight Stadia Reading 0.710, 1.005, 1.3000 ??? k C (5) RL of Station A 100 0.36 104.580m 90 0 (5) b) Two parallel lines are to be connected by a reverse curve, each section having the same radius. If the centre lines are 8m apart, the maximum distance between tangent points is 32m, find the maximum allowable radius that can be used. Derive the relationship between various elements of Simple curve. a) List the factors that affect the selection of triangulation stations. (5) b) Observations were made from instrument Station A to the signal at B. The sun rays make an angle of 60º with the line BA. Calculate the phase correction if (i) The observations was made on the bright line (ii) The observation was made on the bright portion. The distance AB is 10km and the diameter of the signal is 15cm.

Q5 a) What is weight of quantity? How would you allocate weights to different quantities? Discuss various laws of Weight. Find the most probable value of angles A and B from following observation equations. A = 40º 15´ 21.4´´ , B = 45º 12´ 18.4´´, A+B = 85º 27´ 45.2´´ (5) Directions are observed from a satellite station S, 200m from station C, with the following results : A = 000 00’ 00’’ B = 620 15’ 24’’ C = 2800 20’ 12’’ If the approximate lengths of sides AC and BC are 25,200 m and 35,500m respectively. Calculate the angle ACB. Briefly explain the horizontal control and vertical control for setting out. (5) (5) b) Derive an Expression for the scale of a vertical photograph. A vertical photograph is taken over a flat terrain from an altitude of 1800m above datum (M.S.L.). If the elevation of the ground is 300m, determine the scale of the photograph. The focal length of the camera is 152mm.
